Create Controls At Runtime

We are going to create a link control and an image control one next to each other. First we have to set which control we are going to create, so in the form class area place:

private PictureBox PicBox;
private LinkLabel Blue;

Now when you want to create the link and picturebox call this

//CREATES AN EVENT HANDLER FOR THE LINK
EventHandler handler = new EventHandler(LinkLabel_Click);

//BUILD CONTROL LINK
Blue = new LinkLabel();
Blue.Text = "Link Control";
Blue.Location = new Point(30, 20);
Blue.Size = new Size(150, 20);
Blue.LinkBehavior = System.Windows.Forms.LinkBehavior.HoverUnderline;
Blue.Click +=handler;
//CREATES AN NEW PICTUREBOX AND FILLS IT WITH A ICON
PicBox = new PictureBox();
PicBox.Image = Image.FromFile(@"c:\pic.ico");
PicBox.Top = 20;
PicBox.Width = 16;
PicBox.Height = 16;
PicBox.Left = 10;
//ADD CONTROLS
Controls.Add(PicBox);
Controls.Add(Blue);


You created a handler for the click event of the link button so you could now could this in:

private void LinkLabel_Click(object sender, EventArgs e)
{
    //SPLITS THE DATA SO U CAN GET THE TEXT , U COULD PARSE IT THROUGH A CASE STATMENT FOR DIFFERENT SELECTIONS
    string Data = Convert.ToString(sender);
    string [] Split = Data.Split(new Char [] {':'});
    MessageBox.Show("Link Clicked :" + Convert.ToString(Split[1]));
}


If you wanted to create a list of controls you could use the panel control and set the autoscroll property to true so everytime another control is added with a larger top value the scrollbar would appear giving the user the impression of a list control. You can add controls to a panel control simply by putting

panel1.Controls.Add(PicBox);
panel1.Controls.Add(Blue);
